- The best source that I have for that is the IC-Master databook. It
- is released on a yearly basis, and has a section showing the logos the
- manufacturers use on the chips, and which manufacturer is associated with it.
-
- I haven't looked at a recent one, but the ones from a few years ago
- are quite helpful with things like the 3B1.
-
- The book is quite expensive (as you would expect for something about
- three inches thick with a shelf-life on one year), but distributors will
- often deeply discount the old ones when the new ones come out.
-
- Good Luck
